Abstract:
5-Cyano-1-hydrocarbylpyrrole-2-acetic acid is converted to 5-acyl-1-hydrocarbylpyrrole-2-acetic acid by reaction with a Grignard reagent followed by hydrolysis. The cyano compound, novel per se, is produced by reacting 1-hydrocarbyl-2-(2',2',2'-trihalo-1'-hydroxyethyl)pyrrole with a cyanating reagent under basic conditions. The latter pyrrole is in turn formed by reacting 1-hydrocarbylpyrrole with trihaloacetaldehyde such as chloral, preferably in the presence of added organic acid catalyst.
Abstract:
Benzylpyrrolylmethyl esters of ether and thioether substituted cyclopropanecarboxylic acids, synthesis thereof, and intermediates therefor, such esters being useful as pesticides.
Abstract:
Tertiary amines may be prepared by reacting an olefinic compound, carbon monoxide, hydrogen and a heterocyclic compound containing at least one nitrogen atom which possesses at least one hydrogen atom in the presence of a rhodium- or ruthenium-containing catalyst at temperatures in the range of from about 50.degree. to about 350.degree. C. and a pressure in the range of from about 10 to about 300 atmospheres. The reaction may be exemplified by reacting undecene, carbon monoxide, hydrogen and morpholine in the presence of rhodium chloride to prepare N-dodecylmorpholine.
Abstract:
Loweralkyl 1-methylpyrrole-2-acetates are prepared by the recuction of loweralkyl .alpha.-imino-1-methylpyrrole-2-acetates using a divalent sulfur reducing agent.
Abstract:
Enhancement of the flavor of foodstuffs is achieved by the addition of an effective flavor-modifying amount of an aromatic sulfur compound of the formula: ##STR1## wherein R.sub.1 is hydrogen, hydroxy, alkoxy or alkyl and R.sub.2 is hydrogen or alkyl; ##STR2## wherein R.sub.1 is hydrogen, hydroxy, alkyl or alkoxy, R.sub.2 is hydrogen or alkyl, R.sub.3 is alkyl or benzyl and n is 0, 1, or 2; and ##STR3## wherein R is alkyl or phenyl.
